The FATRAFOL 823 is an unreinforced membrane based on plasticised PVC. It is intended as a geosynthetic insulation for use in the construction of sumps and landfills for liquid and solid waste. The membrane is suitable for insulating secondary tanks and sumps for agricultural waste products and for storage of inorganic and industrial products whose chemical action corresponds to the resistance of the film.
Unreinforced membrane based on plasticised polyvinyl chloride (PVC-P).
The membrane has a brown top layer and a smooth matt surface.
The ground waterproofing membrane also forms a radon barrier.
Excellent chemical resistance to the vast majority of inorganic acids, alkalis and their salts.
Compatibility ensures the mutual fit of all system components.
Thickness | Width (mm) | Length (m) | Quantity (m2) |
|---|---|---|---|
1,5 | 2000 | 20 | 40 |
2,0 | 2000 | 15 | 30 |
The membranes may be installed on construction sites only by specialised, suitably trained companies. The membranes are applied in accordance with the principles set out in the FATRAFOL-H construction specification.
